Technology Questions

The Bug Tracking System role is discussed below:

- Testers and developers can know the status of the bug at every stage.

- Changes to the Status will be available to all team members.

- Developers and Testers can easily interact with bugs.

- Repetition of bugs will be avoided.

- Easy to distribute the bug among the developer.

- It will act as a centralized one for defects.

- AIDL is the abbreviation for Android Interface Definition Language. 

- It handles the interface requirements between a client and a service to communicate at the same level through interprocess communication. 

- The process involves breaking down objects into primitives that are Android understandable.

AIDL supports following data types:

- String

- List

- Map

- CharSequence

- All native Java data types like int,long, char and Boolean

- The easiest difference is static HTML once rendered cannot be changed on the other hand dynamic HTML can be changed.

- Static web pages cannot have database access but dynamic pages can be connected to database.

- Using static HTML no interactions persist between user and server but dynamic HTML has capability to interact with the user.

- Static HTML does not require server side coding but dynamic HTML requires server side coding.

- No animation, games can be developed using the static HTML but on the other hand dynamic HTML can perform this task.

$filename = "/home/user/guest/newfile.txt";
$file = fopen( $filename, "w" );
if( $file == false )
{
echo ( "Error in opening new file" );
exit();

}
fwrite( $file, "This is a simple test\n" );
fclose( $file );

HTML language is a set of markup tags. The code used to specify the formatting are called tags. Markup languages are designed for the processing, definition and presentation of text. The language specifies code for formatting, both the layout and style, within a text file. 

HTML is an example of a markup language to improve the appearance of, and link text with data on the internet.

The following are the benefits of using ADO.NET in .NET 4.0 are as follows:

 =>   Language-Integrated Query (LINQ) - Adds native data-querying capabilities to .NET languages by using a syntax similar to that of SQL. This means that LINQ simplifies querying by eliminating the need to use a separate query language. LINQ is an innovative technology that was introduced in .NET Framework 3.5.
 =>   LINQ to DataSet - Allows you to implement LINQ queries for disconnected data stored in a dataset. LINQ to DataSet enables you to query data that is cached in a DataSet object. DataSet objects allow you to use a copy of the data stored in the tables of a database, without actually getting connected to the database.
=>   LINQ to SQL - Allows you to create queries for data stored in SQL server database in your .NET application. You can use the LINQ to SQL technology to translate a query into a SQL query and then use it to retrieve or manipulate data contained in tables of an SQL Server database. LINQ to SQL supports all the key functions that you like to perform while working with SQL, that is, you can insert, update, and delete information from a table.
=>   SqlClient Support for SQL Server 2008 - Specifies that with the starting of .NET Framework version 3.5 Service Pack (SP) 1, .NET Framework Data Provider for SQL Server (System.Data.SqlClient namespace) includes all the new features that make it fully compatible with SQL Server 2008 Database Engine.
=>   ADO.NET Data Platform - Specifies that with the release of .NET Framework 3.5 Service Pack (SP) 1, an Entity Framework 3.5 was introduced that provides a set of Entity Data Model (EDM) functions. These functions are supported by all the data providers; thereby, reducing the amount of coding and maintenance in your application. In .NET Framework 4.0, many new functions, such as string, aggregate, mathematical, and date/time functions have been added.

To access the global data which is originating externally, the super globals are used. The superglobals are available as arrays. These superglobals represents the data from URLs, HTML forms, cookies, sessions and also the web server. For this purpose, $HTTP_GET_VARS, $HTTP_POST_VARS are used. The super globals are pretty good enough to be used in functions. The following are the list of super globals.

$_GET, $_POST, $_COOKIE;$_REQUEST, $_SERVER, $_SESSION, $_ENV, $_FILE

Another PHP Superglobal, called $GLOBALS; is available for persisting every variable with global scope.

to access non-public data outside class getter methods be defined but we cannot define a  method inside interface we can declared a method inside interface.
